What is cancer? (please make sure to include mitosis and cell division)
saw5 [17]

Answer:

<h2><em>Cancer is a disease in which abnormal cells divide uncontrollably and destroy the body tissue. // Putting it into simple words, It’s an error caused in meiosis and cell division.</em></h2><h2 />

WELL here's what it does to your body... (please read all of it...thank u)  

Let's start with what is cancer? Cancer is an uncontrolled growth of abnormal cells in the body. Cancer is caused by a mutation in DNA cells. The DNA inside a cell is packed into a large number of individual genes. Those genes in the cell, each contains a set of instructions telling the cells what types of functions to perform as well as how to grow and divide into more cells. Kind of like a little increased cell factory like system. Errors in the 'instructions' can cause the cell to stop its normal work and functionality and allow a cell to become cancerous.  

Soo... gene mutations can instruct healthy cells to allow and naturalize excessive growth or rapid growth in cells to divide. So then all the new cells are infected and mutated. It can also fail to stop unhealthy rapid growth. Basically, cancer cells lose control in the factory and basically keep on spreading and growing an unhealthy amount till it gets deadly. Just kidding but basically thats what it means. AND gene mutations also make "mistakes" when they try to fix DNA errors. Which then are lead to turn into cancerous cells.  

Now, what causes gene mutation? Gene mutation can be caused by one of many reasons. Two of the main reasons is being born fresh out your mommas womb. You could be born with a genetic gene mutation you most likely inherited from your parents. OR it could be caused by the enviroment you live in. Causes such as smoking, radiation, obesity, harmones, etc. and a lack of exercise.  However, cells contain a mechanism that recognizes when a mistake occurs and repairs the mistake. But occasionally, a mistake is missed... which therefore results in a cell becoming cancerous.

MEANING:

Cancer is bad for your body. periodt.
